A tool which all users should have, above all if you often work with PDF files, is one that lets you extract the text from a PDF and save it in other formats. One such tool is this Office Convert PDF to Doc Text RTF.
With Office Convert PDF to Doc Text RTF you can get the text from any PDF document and save it in DOC or RTF from MS Word or, if you prefer, directly into TXT plain text. To be able to use this application you need to install neither Adobe Acrobat nor Adobe Reader.
Office Convert PDF to Doc Text RTF lets you also extract the text from encrypted PDFs, and preselect the segment of the PDF you want to get the text from.
